Be it known that I, CARL E. PETERSON,

a citizen of the United States, residing at Kerkhoven, in the county of Swift and State of Minnesota, have invented certain new and useful Improvements in Plow-Beam Braces;

and I do hereby declarethe following to be' a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a plow beam;

brace and is'particularlydesigned to be used with a gang share plow. The different shares of such plows are usually spaced laterally and arranged, one behind the'other.

; It has heretofore been the practice to brace i the beam carrying the shares with simple arched braces which were bolted to the beam. These braces have proven ineflicient inactual use and the same have become sprung and often broken, resulting in distortion of the plow beams and other parts of the plow when the ground to be broken up has been hard and refractory.

It is an ob ect of this invention, therefore,

drawn by'powerful tractors and the brace to provide a strong and simple brace for the beams of such a plow which is adapted to be disposed across the top of the same and hold them insecure spaced relation and to be of such design that it will not be readily broken or dislocated.

With this object in view, the invention consists in the matter described and claimed and illustrated in the accompanying drawings, in which like reference characters refer to the same parts throughout the different views, and in which,

Figure 1 shows a standard type of gang plow largely represented in dotted lines and having the novel brace applied thereto;

Fig. 2 is a plan-view of the brace also showing part of the plow beams; and

- Fig. 3 is'a side view of the brace as seen in Fig. 2, showing the plow beam in section,

Referring to the drawings, Fig. 1 illustrates a gang share plow of standard design having the shares 1 carried by the curvedplow beams2. Applicants novel brace is adapted to extend across thetop of, said beam at the top of the curved portion thereof and since the shares aredisposed, one in Application-filed November 12, 1920.

' which'depend pairs of spaced lugs 4. The a space'between the'lugs is made just wide, I

enough to tightly fit along the sides of the plow beam whether the same is made from I-beamcross section or of rectangularisection, and cap plates 5 are provided to be securely bolted-to the lower portions of these lugs 4 by suitable cap screws. The plow beam and brace are thus firmly and rigidly secured together and there is no possibility of lateral or twisting movement of the plow beam. As the brace extends diagonally across said beam, the lugs and the sides of the same thus extend at an angle to the length of the brace, and the ends of the brace are made parallel with the sides of the plow beams. If desired, a filler brace 2% may be placed alongside of the I section or channel section forming the beam to 'insure a firm engagement of the same with the side of the lug 4, as shown in Fig. 3.

While the brace can be made of any 'de-.

sired material, it is preferably made as a heavy steel forging or casting. .The gang plows for which the brace is designed, are

subject to heavy duty and are usually.

1s, accordingly, made very strong and vention, which consists in the. matter shown and described and set forth in the appended claims. f v

jWhat I-claim is: g

1. -A low beam brace for a gang plow comprising a longitudinal member adapted to extend across the'beams of said plow at an intermediate point thereof and having pairs, ofv spaced lugs dependingtherefrom and adaptedto tightly embrace said beams, and plates connecting the. lugs of each pair boltedthereto and disposed beneath said plow beams, to tightly and rigidly inclose said beam.

2. A plowbeam brace comprising a longitudinal member adapted to extend across said beams diagonally andhaving spaced pairs of lugsdepending therefrom adapted; to tightly and rigidly inclose said beam, said lugs extending across said longitudinal member at an angle thereto, and clamping plates bolted to the bottom of said lugs.

" 3. In a gang plowhaving a plurality of downwardly curved. beams, a beambracing pair tovtightly and rigidly i nolose the said member adapted to extend across the said. beam; 1 f w' beams substantially at the highest point In testimon whereof I afiix'my signature thereof and having spaced pairs of angular in presence. 0 two witnesses;
